Document Summary

Class of compounds that is not a protein. Formula (ch2o)x chains usually go from 3-8, most common is 6 (c6h12o6) Aldehyde (on the end) or ketone (in the middle) on one end. Aldehyde and alcohol have the same h2o formula, but are very different. One end looks like either an aldehyde or ketone aldose or ketose. At the other end you have a non chiral carbon. (last chiral carbon). Epimers differ at only one chiral center. Only differ from glucose at one point; reversed at one chiral center. Each carbon has a chirality, and overall they add up to influence the overall chirality. Note: mannose and galactose are not epimers because they are different from 2 chiral centers (2 and 4) Double bonds of aldehyde and ketones can react with alcohols sugars can react with themselves (alcohol of one end and aldehyde/ketone of the other) Alcohols reacting with reactive carbons carbonyl group is prone to.
